Hematophagous bats are fascinating mammals due to their social structure and complex anatomical and physiological characters. We present evidence of the potential use of the giant armadillo ( Priodontes maximus ) in the feeding spectrum of the common vampire bat Desmodus rotundus . Observations were made in the Parque Sesc Serra Azul, located in the municipality of Rosário Oeste, Mato Grosso, Brazil, using camera traps. Although hematophagous bats use native prey in nature, records of this...

We present a record of pampas cat for Magallanes and Chilean Antarctic Region, Chile (51° 00’ 23,03” S; 72° 36’ 45,15” O), this being the first confirmed report of the species in the Region since the 1980’s. The record was obtained as part of a carnivore monitoring program in Cerro Guido ranch which started in January 2019, and included 63 camera-trap stations and a sampling effort of 10,422 trap/nights.

Based on four sites in a subtropical moist forest in southern-central Honduras, the diversity of bats in Sabanagrande was estimated. A total of 29 species from four families were recorded which, added to the historical records, shows 25.7% of the bats recorded for Honduras can be found in the area. The area is important for the conservation of threatened species at local and regional levels, which includes Artibeus inopinatus Davis & Carter, 1964, Lonchorhina aurita Tomes, 1863, Mormoops...

Leucism consists of the partial or total loss of pigmentation in a species. This study reports the first record of leucism in T. brasiliensis for San Juan province, and the second for Argentina. The leucistic individual, a male with white spots on the back, was captured using a mist net in December 2019 in the Ullum departament. These pigmentary disorders are relevant and necessary for ethological, ecological and genetic studies.

A new record for Lasiurus blossevillii (Lesson & Garnot, 1826) from southeastern Buenos Aires province is presented. This record corresponds to a specimen deposited in the mammal collection of Museo Municipal de Ciencias Naturales “Lorenzo Scaglia”, collected in the city of Mar del Plata, General Pueyrredon District. This work expands the geographical distribution of L. blossevillii ca. 142 km to the southeast of Buenos Aires Province.

Although Trachops cirrhosus (Spix, 1823) is known for feeding on frogs, most of the data on its feeding behavior comes from the analysis of stomach contents, remains on roosting sites or experimental feeding in captivity, with few cases observed directly in the field. Here we report T. cirrhosus preying upon the frog Leptodactylus macrosternum Miranda-Ribeiro, 1926, which is the first record of this bat species preying an anuran in southeastern Brazil, and also the first direct observation of a...

In the present study we report the presence of Necromys obscurus (Waterhouse, 1837) in Estancia and Natural Reserve Paititi, located in southeastern Buenos Aires Province, Tandilia System. Individuals were captured in live traps, and most of the records came from areas dominated by native grasses. On the other hand, we warn about the possible danger of the advance of the invasive species Acacia melanoxylon on these natural grasslands, as no individuals were found in places dominated by this...

The neotropical otter Lontra longicaudis Olfers 1818, is a medium-sized carnivore with a wide distribution in America. It generally inhabits riparian habitats between 0 and 1,700 m above sea level. In Ecuador, it occurs in tropical and subtropical areas East and West of the Andes. In this note we report a new locality in the inter‑Andean valley of southern Ecuador, that confirm its presence in ecosystems with temperate and high-Andean climates.

In January 2011, a brown-throated three-toed sloth, Bradypus variegatus , was observed in an Atlantic forest area from Rio de Janeiro, southeastern Brazil. The individual presented a blackish fur, indicating a melanic condition. This is the first record of melanism for this species, and I discuss possible behavioral consequences related to this chromatic disorder.

We describe a group of Dwarf Little Fruit bats ( Rhinophylla pumilio ) using the Buriti palm ( Mauritia flexuosa ) as day roost in a Cerrado area in Cuiabá, Mato Grosso, Brazil. With ten individuals roosting under a dry Buriti palm leaf, we estimate that the group was composed of five females and their young. This is the first record of R. pumilio using leaves of M. flexuosa , and the third publication reporting the use of leaves of this palm as shelter by Phyllostomidae fruit bats.

Dasypus novemcinctus has a large geographical distribution and can occur in a wide range of habitat types. There are few studies about their ecology within the Neotropical region. Studying the mammal community using camera traps in an island of Rio de Janeiro state, Brazil, we recorded an agonistic behavior between two individuals of D . novemcinctus . This kind of social interaction is part of the species’ behavioral repertoire, but this is the first record in the wild in the Neotropical...

We document the first case of alopecia in the black Myotis bat Myotis nigricans (Schinz, 1821) in an urban environment of Colombia. This finding corresponds to a juvenile male with almost total alopecia in the dorsal and ventral areas of the body. The possible causes of the condition are discussed, and we highlight the importance of monitoring bat populations in cities.

Large and medium-sized mammal species are important from an ecological, conservation, and socioeconomic perspective. In southern Mexico, camera trapping in community-based wildlife monitoring projects provide records that extend the range of jaguar Panthera onca (Linnaeus 1758), tayra Eira Barbara (Linnaeus 1758), and paca Cuniculus paca (Linnaeus 1766) for the central area of State of Oaxaca.

In this paper we present five new localities for the Brown Brocket and three for the Collared Peccary in the province of La Rioja, which expand their known distribution range in the province. The records were made through the use of camera traps, and by direct observations. A brief discussion is presented regarding the relevance of these records for the conservation of these species, and the general knowledge of the mammals that inhabit this province.

The chiropterofauna of Corrientes province is one of the least known of Argentina. In this contribution, eight new localities are reported for eight species, belonging to the families Phyllostomidae, Vespertilionidae and Molossidae. In addition, we added some of those species for localities already known for other species. All these records correspond to 31 specimens from different ecoregions (Chaco Húmedo, Campos y Malezales, and Esteros del Iberá). Finally, we add some comments on the...

Geophagy involves the consumption of soil to supplement diets and to facilitate digestive processes. We used camera traps to document the use of a salt lick by Linnaeus’s two-toed sloth Choloepus didactylus (Linnaeus, 1758) from December 2014 to November 2015 in a lowland Ecuadorian forest. We obtained 201 videos of sloths and analyzed if rain or lunar-phase influenced these visits.

These records were based on tracks, visual records, road kills, camera traps and scientif c collections. These records update and extend the presence of the species beyond the National System of Protected Areas.
